Abstract

The addition of ameliorant materials into the soil on former post-rock mining land was identified as one of the potential approaches in improving soil quality. This study aims to determine the effect of ameliorant materials on the growth and yield of horticultural crops. The study used a Randomized Group Design with five treatments and three. Plants used as indicator plants used two types of horticultural crops (spinach and pakcoy). The treatments consisted of KS0 (Control), KS1 (compost at a dose of 10 t ha-1 + biofertilizer 5 ml L-1), KS2 (compost at a dose of 15 t ha-1 + biofertilizer 10 ml L-1), KS3 (compost at a dose of 20 t ha-1 + biofertilizer 15 ml L-1), and KS4 (compost at a dose of 25 t ha-1 + biofertilizer 20 ml L-1). The results of the research showed that the application of ameliorant material had a significant effect on plant height, number of leaves and wet weight of pakchoy plants, but had no significant effect on plant root length. Treatment with a compost dose of 15 t ha-1 + biofertilizer 10 ml L-1 (KS2) gave the highest results for the growth of Pakcoy plants. The provision of ameliorant had a significant effect on all observation parameters (plant height, number of leaves, wet weight and root length) of spinach plants, where treatment with a compost dose of 20 t ha-1 + biofertilizer 15 ml L-1 (KS3) gave the highest results on growth Spinach plant. These results imply that the ameliorant used can be used as an alternative in improving the quality of former sand mining land. ABSTRAK Penambahan bahan amelioran ke dalam tanah di lahan bekas tambang batuan diidentifikasi sebagai salah satu pendekatan yang berpotensi dalam perbaikan kualitas tanah. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian bahan amelioran terhadap pertumbuhan dan hasil tanaman hortikultura. Penelitian menggunakan Rancangan Acak Kelompok dengan lima perlakukan dan tiga kelompok. Tanaman yang digunakan sebagai tanaman indikator menggunakan dua jenis tanaman hortikultura (bayam dan pakcoy). Adapun perlakuan yang diberikan terdiri dari Kontrol (KS0), kompos ampas sagu dengan dosis 10 t ha-1 + pupuk hayati 5 ml L-1 (KS1), kompos ampas sagu dengan dosis 15 t ha-1 + pupuk hayati 10 ml L-1 (KS2), kompos ampas sagu dengan dosis 20 t ha-1 + pupuk hayati 15 ml L-1 (KS3), dan kompos ampas sagu dengan dosis 25 t ha-1 + pupuk hayati 20 ml L-1 (KS4). Hasil penelitian menunjukkan bahwa pemberian bahan amelioran berpengaruh nyata terhadap tinggi tanaman, jumlah daun, dan bobot basah tanaman pakcoy, tetapi tidak berpengaruh nyata terhadap panjang akar tanaman. Perlakuan dengan dosis kompos ampas sagu 15 t ha-1 + pupuk hayati 10 ml L-1 (KS2) memberikan hasil tertinggi terhadap pertumbuhan tanaman Pakcoy. Pemberian bahan amelioran berpengaruh nyata terhadap semua parameter pengamatan (tinggi tanaman, jumlah daun, bobot basah dan Panjang akar) tanaman bayam, dimana perlakuan dengan dosis kompos ampas sagu 20 t ha-1 + pupuk hayati 15 ml L-1 (KS3) memberikan hasil tertinggi terhadap pertumbuhan tanaman Bayam. Hasil ini memberikan implikasi bahwa bahan amelioran yang digunakan dapat dijadikan sebagai alternatif dalam perbaikan kualitas lahan bekas tambang pasir.

Abstract

Cultivating lettuce (Lactuca sativa L.) using plant growth-promoting rhizobacteria (PGPR) in Sorong Regency is uncommon, limiting production despite the high market potential. This study aims to evaluate the effect of PGPR and identify the optimal concentration to improve lettuce growth and yield. The research was conducted in Malawili Village, Sorong Regency, Indonesia, using a randomized block design (RBD) with four treatments: P0 (7.5 mL/L), P1 (10.5 mL/L), P2 (13.5 mL/L), and P3 (16.5 mL/L). Results revealed that PGPR significantly enhanced growth parameters, including plant height, leaf number, fresh biomass weight, biomass weight per plot, fresh weight for consumption, and root length. Among all treatments, 13.5 mL/L (P2) demonstrated the best outcomes, with plant height reaching 14.6 cm, fresh biomass weight of 633.3 g, and root length of 9.6 cm. PGPR application at appropriate concentrations effectively stimulates growth, increases nutrient uptake, and improves yield. These findings underline PGPR's potential to enhance lettuce production sustainably.

Abstract

The concept of viral stealth marketing has been actively used by marketers to make products well received in society. Stealth marketing is one of the digital marketing strategies that advertises a product or service to someone, without them realizing that they are becoming a marketing object. Stealth Marketing is more commonly found on social media platforms today such as Facebook or Instagram compared to traditional advertising media such as newspaper, TV and radio broadcasts. Influencer as a service provider is becoming more general in this method of marketing. Cosmetic products are products that are often marketed with the viral stealth marketing method. Recommendations of cosmetic products from people we know will be easier to accept. Data collection was carried out by conducting a survey on the age group of Gen Z. Data processing using paired t-test and F-test. The results of the paired t-test found that there was a difference in the buying interest of consumers who received product promotion treatment (B1) with the group of consumers who received agent recognition treatment (B2) with a significance value of 0.000. Meanwhile, the results of the F-test show that the presence of agent recognition treatment affects consumers' buying interest in indicators of seeking information, trying products, knowing more, and the desire to own products. This result indicates a change in the buying interest of consumers to cosmetic products when they are aware of the use of viral stealth marketing promotion methods.

Abstract

The research analyzes the educational experiences of rural junior high school Indonesian language teachers by examining their teaching competence improvement barriers. A qualitative method enabled researchers to obtain data from classroom observations together with in-depth interviews and focus group discussions involving twelve teachers who teach at different rural educational facilities. Research demonstrates that rural teachers experience important barriers because they face restricted access to basic resources together with restricted access to professional development and technological support. Despite these obstacles, teachers employ various strategies for self-improvement, such as peer collaboration, online learning, and community support. Rural teachers receive essential help from neighborhood residents who provide facilities along with encouragement to bridge their educational deficiencies. This research demonstrates both the significance of nonformal professional support systems used by teachers as well as their ability to cope with their individual teaching situations effectively. Rural schools need both enhanced organizational backing and stronger community involvement to build teacher qualification levels which produces better academic outcomes in their areas. The study contributes to research overlooking rural education while providing concrete suggestions for authorities and education leaders to enhance teacher development in underserved rural regions.
